The ultimate number of performance shares to be earned will be between zero and 132,227, depending on a combination of service, performance and market conditions.
The Company’s non-qualified stock options, RSAs and RSUs are equity awards with service-only conditions and are accordingly expensed on a straight-line basis over the vesting period. For awards with performance conditions, the Company uses the graded-vesting method of expense attribution. Compensation expense is recorded net of estimated forfeitures, which are adjusted as appropriate.
